Have you ever wondered if the left and right sides of front and rear Glock frame rails are one-piece parts built into the frame or are they separate parts? If you are not a Glock engineer and don’t know how exactly the frame is made, you probably can’t answer that question unless you try to destroy the frame to find it out. But don’t worry, you don’t have to do that. Lenny Magill, the owner and CEO of GlockStore.com, did that for us by cutting in half a Glock 17 frame and discovering that the rails are indeed one-piece parts.
As seen in the images of this article, the left and right sides of both the rear and front rails are connected to each other. Well, to be more precise, they are a single part molded into the polymer frame. There should be at least three reasons for this. First, such a part will ensure perfect parallel alignment of the rails which could possibly be harder to achieve if the left and right rails were separate pieces. Second, such a solution should make it virtually impossible for the rails to come loose over the time. And last but not least, this design should add quite a bit of structural strength to the frame.
It is also interesting to note that the geometry of the rails inside the frame is quite different. The front one has a very thin connecting portion and the rear one looks to be made of two such thin connections which are designed to fit the geometry of the rear portion of the frame.
